TO ALL WHOM IT MAY OONCERN:

Be it known that I,` JOHN M. Gasthof. Worthington, in the -county ofFranklin, and State of Ohio, hare invented a. new and useful Improvementin Angular Shaft-Coupling, and I do hereby' de clare that the followingis a full, clear, and exact description thereof, which will enableothers skilled in the art to make and use'th'e same. reference ybeinghad to the accompanying drawings, forming part of this specification.

Figure l is a. top view of the adjacent ends of two shafts connected bymy improved coupling. Figure 2 is a side view of thesame, partly insection, through the line woz, g. 1. Similar letters of referenceindicate corresponding parts. Y My invention has for its object toimprove the construction of my angular shaftcoupling, patented March 10,1868, and numbered 75,364, so as to make Ait simpler and cheaper inconstruction, and equally efficacious in use; and it consists in theconstruction and combination of various parts, as hereinafter more fullydescribed. .A nndB represent two shafts, which may meet each other atany desired angle. To the adjacent 'ends ofthe shafts A and B are keyed,or otherwise securely attached, clevises or forks, C, between the endsof the forks or arms of which are pivoted the connection-bars, D, by apin or bolt passing through the said ends ofthe -said arms, and throughthe centre of the said bars D. The connecting-bars D are made solid, andupon their ends are cast segmental cogs, E, the teeth ot;A which .meshinto each other, as shown in figs. 1 and 2. The segmental cogs E areformed with a flange or rim npon the outer'sides ofthe one segunda angeor rim' upon the inner side of, the other set, which said flanges causethe said segmentalvcogs to always work insline, and they also receivethe side pressure, thus relieving the connecting-bars, F, in a. greatdegree, from the side pressure.

F are two connecting-hars, to the ends of which are pivoted the ends ofthe bars D, as shown in'iigs. 1' and so as to`ho-ld the segmental cogsalways in gear with each other, at whatever angle the shafts may meet.

, By these improvements the coupling may be made smaller, requiring lessmaterial, and being more easily made, while, at the same time, it workstrue and perfectly easy in every position.

I claim as new, and desire to secure by Letters Pat`ent----4 1. Formingthe bars D, upon which the segmental cogs E are cast solid,substantially as herein shown anddescribed, and for the purposeset'forth.

2. Forming rims or flanges uponthe sides of the segmentalv cogs E, forthe purpose of preventing their lateral movement, and relieving the sidepressure upon tlic connecting-bars I", as herein shown and described.
